Notes 1. Significant environmental events are non-compliances that have a high potential for regulatory action or cause severe environmen tal or health impacts, or are determined to be significant by OPG’s President and Chief Executive Officer. 2. Environmental infractions are non-compliances that have moderate potential for regulatory action and/or intrusive involvement. 3. Environmental penalty orders are monetary penalties that companies may be required to pay if they have violated requirements under the Ontario Water
3 2. Environmental infractions are non-compliances that have moderate potential for regulatory action and/or intrusive involvement. 3. Environmental penalty orders are monetary penalties that companies in Ontario may be required to pay if they have violated requirements under the Ontario Water Resources Act or Environmental Protection Act that are specified in an environmental penalty regulation. 4. Business unit emissions data may not equal totals due to rounding. 5. OPG's mercury emissions have been zero since the company ended coal-fired operations in 2014. 6. For detailed information about OPG's releases to air, water and land, visit Environment and Climate Change Canada’s National Pollutant Release Inventory (NPRI) website at www.ec.gc.ca/inrp-npri. NPRI data for 2018 and 2019 was not available at the time of publishing. 7. The results of annual emissions testing performed at OPG’s Waste Volume Reduction Facility have indicated the facility is in compliance with Ontario air quality standards. The Ontario Ministry of the Environment, Conservation and Parks exempted OPG from testing in 2018 and 2019 due to incinerator outages. 8. Detailed radiological emissions data reports are available at www.opg.com/reporting/regulatory-reporting. 9. Detailed information about OPG’s Environmental Monitoring Programs, including an assessment of radiation doses to the public, is available at www.opg.com/reporting/regulatory-reporting. 10. OPG classifies its spills that are reportable to a regulatory authority based on the actual or potential impacts to plants, animals, human health and safety, conduct of business, and use of property. OPG’s spill categories align with Ontario Ministry of the Environment, Conservation and Parks regulatory requirements for the classification of contraventions. 11. OPG has partnered with Indigenous communities on the Lac Seul Generating Station, the Lower Mattagami River hydroelectric project, the Peter Sutherland Sr. Generating Station, Nanticoke Solar, and the Giizis Energy Solar Storage Micro Grid. 12. Represents 100 per cent of revenue earned from facilities in partnership with Indigenous communities. 13. OPG began using Total Recordable Injury Frequency (TRIF) as a key safety metric in 2018 instead of All Injury Rate (AIR). The TRIF metric is more widely used by other industry sectors than the AIR metric which allows for easier benchmarking. 14. OPG acquired the Eagle Creek subsidiary in 2018. 15. The purpose of the Serious Injury Incidence Rate (SIIR) metric is to capture a more serious sub-set of injuries, ensuring OPG maintains sufficient focus on high consequence hazards that can have life changing impacts for employees. 16. Number of regular employees as at December 31. Regular employees include regular full-time, regular part-time and probationary. 17. Most of OPG’s regular employees are represented by two unions, the Power Workers’ Union and the Society of United Professionals. 18. OPG placed the Nanticoke solar facility into service in 2019. 19. OPG retired the Pickering Wind Turbine in 2019. 20. As of 2019, OPG has 23 hydroelectric generation facilities certified to UL 2854-2018, Standard for Sustainability for Renewable Low-Impact Electricity Products. 21. Nuclear unit capability factor represents energy generated, adjusted for external constraints such as transmission or demand limitations, as a percentage of potential maximum generation over a specified period. 22. Hydroelectric availability represents the amount of time generating units are capable of providing service as a percentage of the total time for a respective period. 23. Equivalent forced outage rate represents the amount of time that generating units are forced out of service as a percentage of the amount of time available to operate. 24. Total employee compensation as per T4s and T4A forms. 25. Payments to the Province include payments in lieu of taxes, gross revenue charges, and current income tax payments.
